Improvement in machines for packing flour



UNITED STATES PATENT OFFICE.

H. A. BARNARD, OF MOLINE, ILLINOIS.

-IMPROVEMENT IN MACHINES FOR PACKING FLOUR.

Specification forming'part of Letters Patent No. 67,2119, dated July 30,1867.

To all whom it may concern:

Be it known that I, H. A. BARNARD, of Moline, Rock Island county,Illinois, have invented anew and Improved Flour-Packer 5 and I do herebydeclare that the following is afull, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use'the same, reference being had to the accompanying drawings, forming parto f this speciiication, in whichf Figure l is a side view of my improvedpacker, partly in section to'show the construction. Fig. 2 is a detailsectional view of the same, taken through the line ax, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved apparatus by theuse of which flour may be quickly, conveniently, and evenly packed intobarrels; and it consists in the combination of the weight, pulleys, andsliding barrel-support with each other and with the upright frame of themachine; and in the combination of the adjustable weight, leverbrake,and friction-wheel with each other and with the pulley-shaft and frameof the machine, the whole being constructed and arranged as hereinaftermore fully described.

Ais the upright frame of the packer, the lower end of which is attachedto the door or platform B. C is the barrel-support, upon the platform c1of which the barrel is set to be filled. The vertical frame c2 of thebarrel-support has tongues formed upon its side edges, which enter andslide in grooves in thel sides of the posts of theframe A, as shown inFigs. 1 and 2.

The platform cl is strengthened by inclined braces extending from theforward corners of said platform c to the upper part of the slidingframe c2.

To the upper part of the sliding frame c2 of the barrel-support C isattached the lower end of a chain or rope, D, the other end of which issecured to the pulley E, attached to the shaft F. The shaft F revolvesin bearings in the frame A, and to one of its ends is attached a pulley,G, from which is suspended a weight, H, by a rope, I, the rope I passingaround the pulley G in a different direction from that in which the ropeor chain D is wound around the pulley E, so that the one ropeor chainmay be wound up as the other is unwound, thereby creating a doubleleverage to counterbalance the barrel as it is being filled with flour.Tothe other end of the shaft F is attached afriction-wheel, J, againstwhich the lever-brake K presses. The lever K is pivot'edlto the side ofthe frame A in such a position that the shoe formed upon its short armmay be pressed against the friction-wheel J, as shown in Fig. l.

L is a weight suspended from the long arm of the lever K in such a waythat it may: be moved backand forth upon the said lever to adjust thefriction upon the friction-wheel J.

M is a brake or shoe, adjustably attached to the frame A, above thefriction-wheel J, by a screw passing through a slot in the shank of thesaid shoe, as shown in Fig. 1.

As thus arranged the eect of the lever K and weight L is to force thefriction-wheel J against the brake-shoe M with a greater or lesspressure, as may be required, the lever K and shoe M forming a compoundor double brake.

By this construction the ilour'may be packed in the barrel evenly andrapidly and more or less solidly, as may be desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

Ihe two pulleys G and E and the compound or double brake K M, incombination with the shaft F, friction-wheel J, weight L, and thebarrel-support C, substantially as herein shown and described, and forthe purpose set forth.
